5 TED Talks on Science That Will Blow Your Mind

5 TED Talks on Science That Will Blow Your Mind
Andrew Maynard is a scientist and emerging technology adviser. He blogs at 2020 Science and tweets as @2020science. Some of the most entertaining, informative and mind-blowing science videos on the web come from TED – the Technology, Entertainment, Design conference. Challenged to give the “talk of their lives,” the world’s top scientists and science communicators have been dazzling audiences – many of whom are thought leaders, trend-setters and entertainers - for years now. Most of the best talks are now freely available on the internet, but sifting through hundreds of video clips to find the real gems can be hard going. To make things easier, here are five of my favorite TED Talks on science. - Was I engaged within the first few seconds? 1. What on earth do coral, complex mathematics and the craft of crochet have in common? 2. Four billion years of evolution have led to organisms that can reproduce, survive the harshest environments, and convert simple chemicals into complex ones. 3.

Blog: The real difference between liberals and conservatives: Jo art From A-ha to OK Go: A museum exhibit all about the music video In the early ‘80s, before MTV turned its attention to reality TV, David Bowie, Madonna and the Pretenders lit up small screens, using a new medium to showcase their songs: the music video. Science Want to know more about the unreliable nature of memory? Elizabeth Loftus studies false memories.

Science Toys Lune A lune is a plane figure bounded by two circular arcs of unequal radii, i.e., a crescent. (By contrast, a plane figure bounded by two circular arcs of equal radius is known as a lens.) For circles of radius and whose centers are separated by a distance , the area of the lune is given by where is the area of the triangle with side lengths , and . In each of the figures above, the area of the lune is equal to the area of the indicated triangle. Hippocrates also proved that, in the figure above, the sum of the areas of the two colored lunes is equal to the area of the triangle (Pappas 1989, pp. 72-73). where the lengths of the horizontal and vertical legs of the triangle are , respectively.

Everywhere in a Flash: The Quantum Physics of Photosynthesis | Wired Science By hitting single molecules with quadrillionth-of-a-second laser pulses, scientists have revealed the quantum physics underlying photosynthesis, the process used by plants and bacteria to capture light’s energy at efficiencies unapproached by human engineers. The quantum wizardry appears to occur in each of a photosynthetic cell’s millions of antenna proteins. These route energy from electrons spinning in photon-sensitive molecules to nearby reaction-center proteins, which convert it to cell-driving charges. Almost no energy is lost in between. “The analogy I like is if you have three ways of driving home through rush hour traffic. Scholes’ findings, published Wednesday in Nature, are the strongest evidence yet for coherence — the technical name for multiple-state existence — in photosynthesis. Two years ago, researchers led by then-University of California at Berkeley chemist Greg Engel found coherence in the antenna proteins of green sulfur bacteria. Images: 1. See Also:

Early stress alters epigenome Scientists have figured out how stress experienced early in life can cause long-lasting changes in physiology and behavior -- via epigenetics.

Top 10 Amazing Biology Videos | Wired Science Cyborgs, stem cells, glowing mice, and hilarious music videos are great reasons to be excited about biology. Here are some of our favorite clips from the life sciences. 10. Immune Cell Chasing a BacteriumIt may look like the predecessor to Pac Man, but this vintage clip shows a neutrophil wending its way through a crowd of red blood cells to destroy its bacterial nemesis. 9. How High Speed Gene Sequencing Works Within the next few years, Helicos BioSciences may be able to read an entire human genome for under one thousand dollars. 8. 7. 6. 5. 4. 3. 2. 1. Last week, regenerative medicine researchers announced that they have grown a new windpipe for a woman who was crippled by tuberculosis. See Also:
